Cannot send email between users.

I have one user (user A) that cannot send email to another user (user B). User B can send email to user A just fine, but when user A hits reply and sends, the email never gets to user B even though Zimbra states the email was sent successfully. I have tried to type in the email manually, replying, replying to all. There is never a bounceback message or anything, its like it goes to the blackhole. Any ideas??

If this is about ZCS you should check the log files to see what's happened to the mail and make sure the recipient doesn't have any filters that manipulate mail from this particular sender.
